     $(function(){ 
 
       var tbody = ""; 
     
     //------------遍历数组 .each的使用------------- 
           var anArray = ['eins','zwei','drei']; 
     $("#result").html("------------遍历数组 .each的使用-------------"); 
           $.each(anArray,function(n,value) { 
            
            alarm(n ' ' value); 
           var trs = ""; 
             trs = "" Wert ""; 
              tbody = trs; 
            }); 
 
          $("#Projekt").append(tbody); 
      
  });

3.jQuery 遍历List集合（其实与遍历一个对象没有太大区别，只是格式上的问题） 

复制代码 代码如下:

     $(function(){ 
 
       var tbody = ""; 
     
     //------------遍历List集合 .each的使用------------- 
      var obj =[{"name": "项海军", "password": "123456"}, {"name": "科比", "password": "333333"}]; 
    $("#result").html("遍历List集合 .each的使用"); 
      Alert(obj);//是个object元素 
   //下面使用each进行遍历 
   $.each(obj,function(n,value) {  
           alarm(n '' value); 
       var trs = ""; 
             trs = "" value.name „ “ value.password ""; 
             tbody = trs;        
           }); 
         $("#Projekt").append(tbody); 
      
  });
